To all whom t may conc/ern,.-

Be it known that I, Enocn WILLIAM BRYAN, a citizen of the United States, resid ing at Valdosta, in the county ot liowndes, State of Georgia, have invented a new and useful l/VheeLRilu for Pneumatic lires; and

I do hereby declare the itollowingi` to be a full, clear, and exact description ot the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved Wheel-rim for pneumatic tires, and one of the objects of the invention is the provision of a Wheel-riin particularly designed for automobile Wheels.

A further object of the invention is the provision of a rim to be mounted on a 'telly of a wheel. This rim is simple, ettieient, practical and durable, and consistsl of i'ew parts, and constructed whereby it. may be easily disassembled or assembled conveniently and with ease.

A further object of the invention, is the. provision of a rim consisting of a pair ot annular sections having clencher tlaugres to engage the-flanges of the outer tire case. and havinginteeengagine' means at their 1ueeting edges, whereby said sections may be 'held in place, in combination with a, band between said sectional rim, and the couventional iorm of felly` there beinejannular rines bolted to the telly to hold the scc* tional rim in place.

A further object of the invention is to provide an annular wear band between the telly ot the wheel and the tire holding rim, ,thereby avoiding,r wear on the wood telly incident to removing the tire holding rim.

A further object oi the invention is the provision of an improved tire holding1 rim consisting ot' two sections joined as hereinafter specified. whereby either one ot" the sections may be easily renewed. For instance, it has been found that automobiles have been run for considerable distance on detiated tires, consequently there is eonsiderable Wear on the clencher flanges ot the rim. sometimes there is more wear on one clencher flange than on the other. and heretotore the entire rim has been removed to be replaced by another, hence it is the aim ot'- the present invention to provide a rim con- Sistine* o't tWov sections. whereby one or the other of the sections may be removed to be replaced by a new section.

ltn practical fields the details ot construen tion may necessitate alterations falling' within the scope oit' what is claimed.

The invention comprises further features and combination ot parts, as hereinafter set forth, showntjwn the drawings and claimed.

Figure 1` is a view in perspective of a telly showing` the improved sectional rim, band. and annular rings applied, and constructed in accordance with the invention.

Fig. E?, discloses perspective views of the various parts ot the rim construction.

Fig. 3 is a perspective view ot' a modified form ot rim construction on a telly.

Fig. 4- discloses perspective views ot the parts of the construction shown in Fig". 3.

referring more especially to the drawings, ldesignates a usual telly. to which the spokes :2 'are connected. y."vurrolnidingr the telly 1 is an annular band the upper face ot which adjacent one edge has an annular cutaway portion 11. The band 3 is provided with an annular recess or groove. 5 substantially tl-shaped in cross section. and 6 de notes a rim. which consists of* the two sections 7 and 8. The section 8 of the rim 6 is designed to be split as shown at 8 in Fig". so that: the section .ti of said rim 6 may be mounted on or slipped over the band 3. These sections are provided with cleucher flanges 9, to engage the flanges 10 otthev Ioutcrvtire casinar 11, which surrounds the inner tube 12. The inner edgeot' the section 7 has a ill-shaped annular tongue 13. to enter the annular 'tl-shaped groove 14 of the inner edge ot tlicsection 8, whereby the inner edite portions ot the sections 7 and 8 are held in place. |lt`he section 8 on its nader face/near its inner edge has a tongue substantallv V-shaped in cross section to engage the recess or groove .5. Bv splitting the sec tion 8 ot the band G. the tongue 15 may engage the groove 5 of the band 3. When the section t" of the rim 6 is slipped or titted over the band 3, and the two sections 7 and ot' the rim 6 clamped in place by the hereinatter set forth annular rings 17, said tlshaped annular tongue will engage the correspondingly shaped groove 14, and prevent the adjoining endotn the section 8 ot the rim G from springing out ot place. lt will `be seen that a raised portion 16 is formed between the cutaway part l and the recess or 2groove 5. rllhe cutaway portion 4 is designed tor the, purpose ot' permitting the section 8 to be telescoped over the band titi 3, and by reason of the beveled surface of the tongue 15, the section 8 may be forced over the raised part; 16 of the band i. After the band 3 and the rini 6 are placed on the elly l, the annular rings 17 are secured to the felly l, by the bolts 1S having nuts 19, whereby 'the elencher flanges 20 of said rings will engage and support: the eleneher flanges 9. ln Figs. 3 ande, the riin G also consists of two sections 2l and 2Q, which have their tongue in grooved connected adjacent edges to one side oi' the center ot `the telly In Figs. 3 and the band is eliminated, and the sections 2l and Q2 of' the rin: t3 have eleneher flanges 251. to engage the t'langges l0' of' .said tire easing l. rlfhe sections 2l and 2:2. are provided with additional annular flanges 25 to engage the opposite sides of the elly l. Clamping plates E2G are used in lieu of the rings 17 and are secured by the bolts 27 and nuts 2S to the elly l. The seetion 22 of the riin (l is seeured by bolts, suoli as indieated at 529 to said felly T he in'v'ention having been set forth, what, is claimed as new and useful is In an improved riin construction, a felly7 an annular band surrounding the saine, a
